Letter is a paper size that is used for a wide range of documents, including magazines, catalogs, letters, and forms. It is also called ANSI A or American Quarto.
Dimensions
A Letter size page measures 215.9 × 279.4 millimeters or 8.50 × 11.00 inches. In PostScript, its dimensions are 612 × 792 points.
Part of the ANSI standard
Letter is part of a set or range of page sizes, called the ANSI/ASME Y14.1 standard. This US standard was established in 1995. Two ANSI A pages next to each other in a spread equals the ANSI B paper size, which is also known as Tabloid or Ledger, depending on the orientation.
Alternatives
A Legal sized document has the same width but is a 14 inch high.
Outside of the USA and Canada, the international ISO 216 standard is used. The ISO-alternative to Letter is called A4 or DIN A4 and measures 8.27 x 11.69″ or 210 × 297 mm.

This is quite useful information, which I think is very important for working with PDFs. I also want to point out that it’s important to choose a good online editor. And recently, I found such a tool after reading https://timesofmalta.com/article/pdf-guru-reviewing-allinone-pdf-solution-platforms-a2.1098065 a PDF Guru review. This editor is quite versatile when used across different platforms. I really like its compatibility and mobile optimization, which, in my opinion, is a very important factor nowadays.
I believe there is a typo here, marked inside the: “**”
**but is a 14 inch high.**
